低入力バイアス電流オペアンプ

Featuring very high-accuracy and stability (V_IO ≤ 25 µV at 25 °C), our TSZ18 series of 5 V zero-drift op amps are ideal for high-accuracy, high-bandwidth sensor interfaces including body-signal monitors, blood-glucose meters, industrial sensors, factory automation, and low-side current sensing. Available in single-channel TSZ181 (1.2 x 1.3 mm DFN6 package) and dual-channel TSZ182 (2 x 2 mm DFN8 package) versions.

With an extended operating range of –40 to +150°C, the TSZ182H is ideal for harsh automotive environments.

The TSV792 operational amplifier offers a high gain-bandwidth product (GBW) of 50 MHz combined with excellent accuracy, which is provided by a maximum input voltage of 200 µV. This ensures high accuracy when amplifying small-amplitude input signals.

The TSV792 is available in a Mini SO-8 package and can operate from 2.2 to 5.5 V in single supply. Fully specified on a 22 pF load and able to handle an output capacitor up to 1 nF, this Op Amp can also be used as an A/D converter input buffer.

 

 

 

The TSV711, TSV712, TSV714, TSV731, TSV732, TSV734 series of single-, dual-, and quad-channel operational amplifiers offers low-voltage operation (1.5 to 5.5 V), rail-to-rail inputs and outputs, and an excellent accuracy (V _IO lower than 200 μV at 25 °C). Housed in the smallest industrial packages, these low-power devices benefit from ST’s 5 V CMOS technology and offer an excellent speed/power consumption ratio associated with an ultra-low input bias current. These characteristics make the TSV7 series ideal for sensor interfaces and active filtering for battery-powered applications in the wearable, portable consumer, medical and industrial segments.
